Anterior boundary: Midline of the neck from chin to the jugular notch Posterior boundary: The anterior margin of sternocleidomastoid: Superior boundary (base) The lower border of the body of the mandible, and a line extending from the angle of the mandible to the mastoid process
The triangles of the neck describe the divisions created by the major muscles in the region.. The side of the neck presents a somewhat quadrilateral outline, limited, above, by the lower border of the body of the mandible, and an imaginary line extending from the angle of the mandible to the mastoid process; below, by the upper border of the clavicle; in front, by the middle line of the neck ...
Like other flexion surfaces of large joints (groin, popliteal fossa, armpit and essentially the anterior part of the neck), it is an area where blood vessels and nerves pass relatively superficially, and with an increased amount of lymph nodes. During blood pressure measurements, the stethoscope is placed over the brachial artery in the cubital ...
The posterior view contains, from superior to inferior, the cervical region encompassing the neck, the scapular region encompassing the scapulae and the area around, the dorsal region encompassing the upper back; the lumbar region encompassing the lower back. the sacral region occurring at the end of the spine, directly above the buttocks.
Lateral (away from the midline), formed by the anterior belly of the digastricus; Medial (towards the midline), formed by the midline of the neck between the mandible and the hyoid bone; Inferior (below), formed by the body of the hyoid bone; Floor is formed by the mylohyoideus; Roof is formed by investing layer of deep cervical fascia
From a lateral aspect, the sternomastoid muscle is the most striking mark. It separates the anterior triangle of the neck from the posterior. The upper part of the anterior triangle contains the submandibular glands, which lie just below the posterior half of the mandible. The line of the common and the external carotid arteries can be marked ...
The head and neck are emptied of blood by the subclavian vein and jugular vein. Right side of neck dissection showing the brachiocephalic, right common carotid artery and its branches. The brachiocephalic artery or trunk is the first and largest artery that branches to form the right common carotid artery and the right subclavian artery.
Anterior (from Latin ante 'before') describes what is in front, [22] and posterior (from Latin post 'after') describes what is to the back of something. [23] For example, for a dog the nose is anterior to the eyes and the tail is considered the most posterior part; for many fish the gill openings are posterior to the eyes but anterior to the tail.
